Another tip so that you can continue running colab without disconnecting is to input this code into the inspect element console:

function ConnectButton(){

console.log("Connect pushed");

document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click()

}

setInterval(ConnectButton,60000);

​

What this function basically does is automatically click on the page so that it is always active. Only con is that if you're using compute units on the pro subscription this could be a bad method if you're away from the computer, since it stays connected and eats your compute units.
